Question

the area of square field is 625 metre square A man cycles along its boundary at 5 metre second in how much time will be will he returned to the starting point​

Answer 1

Answer:

Area of square field =625 cm sq

side of square field=25 cm

perimeter of square field=25x4=100

speed of man=5m/s

time he will take to return to the starting point=100/5=20seconds

Answer 2

Step-by-step explanation:

Area of the field =625 metres square

Side * Side =625 sq. metres

Side square =625 sq. metres

Side = √625

Side = 25 metres

The man is cycling along the boundary of the square field , it means he is cycling along the perimeter of the square field.

Perimeter of the square field =4* side

=4*25

=100 metres

So distance he had travelled when he completes one round=100 metres

Speed of the man=5 metres/sec

Time =Distance/Speed

Time=100/5

Time=20 seconds

Therefore total time taken to return to the starting point=20 seconds
